minimum value is 30 minutes. if we set it to 0, we don't automatically update, we can control when the update is done by the Alarmmanager class. as an experimental small example, can be changed to 1 hours, but cannot be set too short, for example 1 minutes, in the simulator experiment, if the time interval is too short will not be triggered.Starting with SDK3.1, users can resize widgets, including horizontal,vertical and none, by pressing the widget.

Just like the "Mo" character Unicode code 0X83AB, press big endian to become 0xab83.BOM (Byte Order Mark):Because of the problem of byte order in Unicode storage, inserting a non-existent character (ZERO WIDTH no-break SPACE) in front of the Unicode text is used as a flag to distinguish between the two kinds of byte-order.

characters. Now the PC platform must support GB18030, the embedded products are not required. So mobile phones, MP3 generally only support GB2312.It is clear that the ASCII code cannot represent all the words and symbols in the world, so it is necessary to create a new encoding that can represent all the characters and symbols, namely: UnicodeUnicode (Uniform Code, universal Code, single code) is a character encoding used on a computer. All characters account for 2 bytes.UTF-

the full lifetime .From OnStart () to OnStop (), an activity instance becomes invisible from the visible state, which is known as the visible lifetime . Note that the visibility is not necessarily at the top of the stack, and therefore must be able to interact with the user.From Onresume () to OnPause (), an activity instance undergoes a process between the active state and the paused state, both of which are active, called foreground lifetimes , or

Setting timeouts can be set up like this: 1 SET lock_timeout; 2 3 SELECT * from production.products 4 WHERE productid=2; Once set, the request time is exceeded, and the call ends. where set (set locktimeout-1) is infinite wait.

The Clinit method is a class constructor method that is not called until the initialization phase of the JVM is loaded.Execution purposes are different: init is the initialization of non-static variable parsing, while Clinit is initializing static variables and static blocks of code.Third, class loaderThe virtual machine takes the "fully qualified name of a class to obtain a binary byte stream that describes this class" in the class load phase, which is implemented outsid
